摘要
针对纹理分割问题,提出了一种在频率域呈环形分布的Gabor滤波器组(Gabor环)的设计方法,在能量意义下给出了自适应选择滤波环带的步骤,并给出了经Gabor滤波后纹理特征的计算公式。根据给定Gabor滤波器环具有的多方向特性对不同纹理图像进行滤波,然后计算滤波后各点特征,并利用这些多方向特征进行纹理分割。实验表明该方法能取得较好的分割效果,并具有很强的通用性。
A design of Gabor filters which are distributed as a ring on the frequency domain is proposed. In the sense of energy, the selection procedure of adaptive filtering ring and feature extraction expression after Gabor filtering are presented. After multi\|orientation filtering with the Gabor ring, texture features of every pixel are derived and segmentation is performed. Experiments show that better results can be obtained.
